碱助剂改性铁基费托合成反应催化剂的研究进展
Research progress on alkali promoters modified iron-based catalysts for Fischer-Tropsch synthesis reaction
摘要
Abstract
Due to the complex reaction mechanisms of Fischer-Tropsch synthesis reaction and the limitation of characterization methods,it is difficult to connect the macroscopic experimental results with the microscale changes,so theoretical calculations are needed to provide theoretical support for experimental research.In view of the extensive application of iron-based catalysts in Fischer-Tropsch synthesis reaction and the important role of alkali metal promoters("alkali promoters"for short)in iron-based catalysts for Fischer-Tropsch synthesis reaction,the research progress on alkali promoters modified iron-based catalysts for Fischer-Tropsch synthesis reaction was reviewed.At first,the active phases of iron-based catalysts for Fischer-Tropsch synthesis reaction and the migration of alkali promoters in the surface phase and bulk phase of the catalysts during carbonization were summarized.Then the effects of alkali promoters on the structures of iron-based catalysts for Fischer-Tropsch synthesis reaction was analyzed,and the theoretical calculation results of promoting effects of alkali promoters on iron-based catalysts for Fischer-Tropsch synthesis reaction(catalyst structure design,reaction path distribution,reactant molecular adsorption and product distribution,etc.)were introduced.Finally,the future development of related fields was prospected.关键词
